I suspect this attitude of “read the fucken manuel” comes from when tooling was simpler and you could actually read all the manuals (or buy a book) to learn every small bit of it. Today, I’d be surprised if someone actually read all the Windows, .Net, and Powershell docs before attempting to write a small script.

Heck, even simpler things like Python have massive docs beneath every layer of them. You don’t learn everything from the ground up anymore, only the relevant parts to your use case.
